LOC - Tight?

[Scottie-TX]

Concerned about a previous use of this product, LOC-TITE, because mos. after applying, it was not hard - I pondered: Hmmmmm. Never got hard?
Stale? Vial open too long? Active ingredient gone? What?
Last eve I put a drop of red from a container opened mos ago next to a drop of blue that I just opened - fresh.
Reads, "shake thoroughly" . "Sets in 20 mins; cures thoroughly in 24hrs."
Nearly 24 hours later, the red is yet a bright liquid and the blue has discolored and only a trace of gelling has occured.
These are LOCTITE "Thread Locker" BLUE" 242, AND "high strength" RED thread locker.
Did I buy the wrong product for clock work?
What?

Scottie,

Both tech spec sheets indicate it cures when removed from air and oxygen.... so your test might not be valid.

Scottie - I believe these are anerobic(sp?) adhesives. That is they won't set until air is excluded, like "crazy Glue". Blue, can be broken apart with some torque. Use red if you never plan to take things apart, although heat will destroy the bond. Hope this helps.

Scottie - I use blue and have no such issues. It hardens in the air and holds fine. I can only guess, but I suspect that one component has separated from the others and only very vigorous shaking will blend them again. What is the material they are on - brass? I wouldn't suspect that that has an effect, but maybe ...?

Well, yes it does help.
It helps because I probably misunderstood it's abilities and as I recall, used it to glue something plastic to a steel shaft. It didn't cure. The conditions for curing were absent and it's not made for plastics.
THANKS.

Scottie,

Loctite is not meant to be used as a glue, only as a thread locker. I use the blue type regularly and also the green type (which is a wicking type) and I find them very effective.

I recently realized that some pendulums might need a bit of resistance on the nut to keep the adjustment from drifting. The green type can be applied without loosening anything, and it works great - so good that you will find it dificult to change the setting and may need pliers to add a bit of 'persuasion' to get it to move.

Hi Scotty. As previously stated loc-tite is not a glue. In the mining industry (I'm a mechanic) we use it every day. Someting like this: Blue for later take apart with hand tools, Red for anything that spins: drivelines, fan blades, ect. Green for anything that does not come apart again, bearing races, collets ect. Also it needs to be a tight fit, as it sets up in the absence of oxygen. Hope this helps. Kevin.
ps. I use blue on watch crowns.

Kevin,
I use blue on watch crowns also. Does an excellent job there.
